exactly,

like this class expression in Protege 4 (OWL2):

(MMC_Cpx some decimal[> "0"^^integer, <= "5"^^integer])
or (MMC_Cpx some decimal[< "10"^^integer, > "5"^^integer])
and MMC_Chr some decimal[< "5"^^integer, > "0"^^integer]
and MMC_Ol some decimal[> "40"^^integer, < "90"^^integer]
and MMC_Opx some decimal[< "60"^^integer, > "10"^^integer]
